FILTER.

Specification of Letters Patent.

Patented Oct. 13, 191 1.

Application filed February 14, 1913 Serial No. 748,343.

To all whom it may concern:

Be it known that I, llIIUHAEL H. MALoNnY,

' a citizen of the United States, and resident of Plymouth, county of Suffolk, State of Massachusetts, have invented an Improvement in Filters, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

My present invention relates to filters adapted either for household and domestic, or for public or for semi-public installations,

being suitable to be readily applied to any required use.

Among the prime objects of the invention are to provide water purifying means, consisting of strainer and filter elements adapted to be easily and quickly assembled in place in a container barrel, and as quickly removed when required'for inspection or cleaning; the filter and strainer elements being for this purpose held assembled by yielding frictional pressure against the sides of the container barrel and being also formed so as to be held in place and,

against displacement by the pressure of the water passing therethrough.

A further object of the invention isto provide a construction of filter and strainer members which combines to a large extent the advantages of the tubular type with the extended filtering surface provided thereby, with the advantages of the flat or plate type of device with its capability of being easily and cheaply stamped out of sheet or plate material.

To these ends the inventionconsists in a, filter barrel preferably of generally cylin-- drical form having a lateral water inlet and outlet opposite each other, and of strainer and filtering means of preferably of generally half round form held assembled in the barrel by the yielding frictional action of the strainer members, and also by the pressure of the water passing there through.

The above and other objects and features of the invention will be better understood from the following detailed description.

taken in connection with the accompanying drawings and will be thereafter pointed out in the appended claims.

Referring to the drawings: Figurel is a side elevation show ng one form of my 1m proved filter; Fig; 2 is a central longitudinal vertical section thereof; and Fig. 3 is a transverse sectionon line of Fig. 2.

The filter casing is formed as a tubular barrel 10 normally horizontal with a water inlet connection 1.1 shown as a usual internally threaded collar at its top, and a discharge nozzle or spout 12 at its bottom and diametrically opposite the inlet. This conter through the filter and strainer members.

The water purifying means which I prefer to employ consists in two half round strainer plates, with an interposed filter pad or like filtering means, which, are, assembled and held pressed together as they are inserted into. the container barrel by yielding spring pressure of the strainer plates aslater more fully described. The lower half round strainer plate 17 ispreferably stamped or struckout of sheet or plate metal of a size to snugly fit the interior of the barrel when pressed thereinto. Thisstrainer plate is preferably formed with struck out projections 18 shown as rounded, at each side,in

position to lie adjacent the extremities of f the dished out formation lii to thus resist displacement of the strainer plate by turning around in the barrel. It will be observed that the rounded character of these projections permits the strainer plate to be pressed to place with a yielding spring action in the barrel, the projections slipping over the slight shoulders at the sides of the dished out formation '15, and the sides of the strainer jyieldingly pressing against the sidesof the container barrel. The filter pad or layer 19 may be of any suitable material forthepurpose, such as a felt pad or other suitable filtering means. This pad. is held securely assembled between the outer filter plate 17 and the inner filter plate 20 with a yielding frictional grip as the members are pressed to place, and the inner plate 20 is outlet, and a half round strainer member covering said outlet formed to engage the sides of said barrel chamber with a yielding fit and having struck out projectlons engaging the sides of said dished out portion.

7. A filter comprising a barrel chamber generally circular in cross section with an inlet at one side, and an outlet at an opposite side, and water purifying means consisting in half round strainer members in nested relation with an interposed filter pad, fitted in said chamber with their convex side toward the water outlet, said strainer members being adapted to hold the filter pad in securely assembled relation by the impact of 15' water against the concave side thereof, but with a capability of easy manualremoval.

In testimony whereof, I have signed m name to this specification, in the presence of two subscribing witnesses.
